Still researching and finding my feet.

Years ago I bought a TX, an Rx, a controller and grid antenna from Giles G1MFG.... I see there has been discussion about folk unearthing them.

My question is are they worth me wiring up and trying 23cm ATV on them as my first step.

I bought them after Giles did a RadCom(?) article ... but we had a sudden move and I never did explore ATV until recent engagement with ATVers has activated the bug.

Meanwhile a picotuner is on the bench too.

I do not see a lot of dvbs fm tv now, it’s all digital dvb s2.

Hi Graham

There is virtually no FM ATV activity on 23 cm now; digital (DVB-S2) is the primary mode as it gives better pictures with less power, and is remarkably easy to generate with a computer and an SDR.

So, I suggest that you press on with the PicoTuner and look in that direction.

There’s a couple of repeaters I think that still TX on FM ….and quite a few that still RX on FM as well as digital .

Have a look on the streamer and most repeaters list the inputs they will receive on .

I see from QRZ that you may be in range of GB3HV when it comes back on ….it lists a 23cms FM input as well as Digital …..

There must be loads of these FM boards kicking around in draws , junk box’s , ….i used to like searching in the noise on the screen for weak signals …….but guess I’m a old dinosaur.

Thanks for the replies ... it is as I thought!
One day there will be a vintage group seeking such items!

Hello Graham,

a lot of analog ATV is still done in Germany.

We use video quad splitters to display four frequencies simultaneously.
With DATV, there's a delay that doesn't occur with analog.
